Now THAT's interesting. I had thought some about how clean to make the interface from the anode to the tab on the transom. But now that you illustrate the issue better, I feel that I may need to put some extra effort into making sure that interface is as low-resistance (electrically) as possible.

Thanks for commenting. The anode is aluminum (1/2" 6x12 plate I cut in half and drilled for mounting), and I think it's working wonderfully. Yes, it's protecting the whole boat, as I think intended by North River Boats. I replace the anode twice a year and it seems to be moderately active. The engin...

Just because I haven't seen the addressed. Are you calibrating the compass on the water underway? Yes, underway calibration. I tried the calibration procedure again yesterday with no better results. At this point it's just an exercise in futility since the autopilot is working reasonably well even ...

Is it consistent or all over the place? I’m not sure, I’ll have to experiment some more. It’s primarily the Garmin autopilot Calibration Value in the Dealer Setup menu which concerns me. It’s gives a number from 0 to 100, with 100 being a magnetically perfect environment. Mine is somewhere around t...

I have a Garmin GHP Reactor autopilot on my North River RAIV with the course computer (heading sensor) mounted below the deck, under the helm area. It works but I’m not able to get very good compass calibration values. Am I fighting a losing battle with a metal boat or should I be looking for other ...

I've been thinking, and dreaming, about aluminum boats for a long time and, I've perused this forum for a long time, learning and gathering information from this vast knowledge base. I thank you all for helping me get to the point of having a plate aluminum boat. I recently took delivery of this 28'...

I'm still new to alloy boats but trying to learn as much as I can. I've been hoping to could find something small to start with, and stumbled across this little boat near me here in Massachusetts. Stopped and talked to the owner today and he is not interested in selling. But, he said the boat was bu...

Longtime lurker, but first time poster here on AAB. I'll use my first post to ask, what happened with this thread? Any more details to share about this boat or any subsequent builds? Sadly, I only own NON ALLOY boats, though I've added a substantial aluminum pilothouse to one of my boats. I see alum...
